    Default Super Singles for 8 Lug MB Trucks (917,1120)

    Would anyone have a US source for 8 lug super singles for the MB trucks like the 917 and apparently the 1120. I just sent an email to Hutchinson in Germany in case they are not available here.

    I think your wheels would be the same as the "big" unimogs - U1700 etc?

    Here is their specs:

    Backset is 104mm
    Centre hub dia : 220mm
    8 Stud
    PCD 275 mm
    Standard Studs 20mm

    There is a company called "Stazworks" which can make you new wheels or recenter mil surplus HMMT or MRAP wheels - www.stazworks.com

    Thanks, one thing I forgot to mention is I would like the rims to be reversible so they could be used front/rear so I would need to carry just a single spare. And since I am wishing I have read that 22.5" tires are easier to source world wide, plus the 20" tires seem to be mostly heavy tread off road and something with a less aggressive thread pattern might be easier on highways.

    A point to remember is, super single tires are drive or trailer tire positions only, they don't make steer tires.
    The design was to replace dual tires.
    Your single spare option being reversible, isn't an option.
    Before you get too far ahead, you will still need tires before you figure the wheel issue.

    I speculate their plan is not ”Supersingles”, but single tyre the rear axel to match the front simply for better efficiency on a camper what wont weigh near original chassis design GVM.

    Btw, dont get too hung up on spares.
    Changing & repairing tubeless tyres is easy. Even leaving wheel attached to axel.
    Unless you have beadlocks or MPTs, I find it easier than wrestling & unbolting/bolting an entire mounted wheel.

    He said he wanted if he could to run one spare that would be reversible allowing it to be for front and rear.
    His idea, not mine. I don't think he was aware of position tires.
    Im not familiar with the truck either, so I don't know if a tire that wide would even fit the front.

    Hiya

    Just regarding tyres, our Mog started with 20" Continental MPT 80 which have a directional lug and were quite noisy and the shoulders wore a little unevenly and may have needed rotating more than they were. No complaints on how they performed on tarmac on an old 150Hp truck.

    Next up were 20" Michelin XZLs which wore less unevely, non-directional, much much quieter and again no complaints.

    I think neither had directional arrows from the manufacturer on the shoulder to suggest they should be mounted either way round. The slight tractor tread V on the 80's could be mounted "backwards" if traction while reversing in mud was more important than driving forwards. But that's a bit of a maybe. The XZL's once aired down were awesome in mud (with portals, long soft coil suspension, flexy chassis, 4x4, three difflocks, amazing driving skill etc etc )

    There's a book and dvd by a German Mog expert called Gisbert Hindenach that looks at the different 20" tyres suitable for a Mog a little more technically, with a grading depending on your expected usage. It mainly covers a Mog off road in all respects, very informative.

    Hi guys, well as you have figured out I am definitely new to these kind of trucks (or any heavy truck for that matter). I am in the process of buying the 1120 and just wanted to make sure getting single wheels was not impossible (or crazy expensive). Now if I did want to carry just a single spare, without reversing the rim would I be looking for a "split rim"? Any idea as to custom steel wheel builder in the USA that could do these?

    Hi

    A Mog we had in the UK had 8 bolt rims which we couldn't find a used one for as a spare until one turned up after being re-centred and then broke. I would think asking a Merc dealer in Europe that deals with older trucks may be able to point you to either some used ones or new from Merc which you know will then fit. Merex or Atkinson Vos maybe?

    A split rim is how a multi piece wheel is constructed, some are described as two piece some as three piece, (ours were three piece but had four if you included the sealing rubber), so to change tyres you maybe don't have to unmount the biggest bit of the wheel from the hub if the wheel is mounted the right way round to do that (dish out).

    If you look at Bill Caid's lovely blog you can see his 1017A that I think had Unimog U500 super single split rims front and back. The front hubs have the wheel dish out, the rears have the dish in to end up with a suitable track width front and back.

    Running singles on all four corners with one reversible spare is the standard for 917, 1017 etc. 20" tires are not readily available in South America. You will want "all position tires" .
